Application filed December 9, 1907. Serial No. 495,797.

To all whom it may concern:

Be 1t known that I, AUGUST ITEN, a citizen of the; United States, residing at Mountaintable life among the crops. 7

The invention is capable of attachment to.

,view, n the county Hawaii, have invented a. new and useful ImIprovement in Weed-Burners, of which the fol o wing is a specification. This invention is an a paratus" designed to destroy weeds, grass an the like by burning,

the primary object being to provide an apparatus which can be used between rows of growing crops, without injury thereto, and utilizing a greater or less fuel burners whose flames are directed down- Wardly to burn and destroy the weeds, together With any insects thereon, and in fact to destroy any obnoxious. animal or vegethe frame of anordinarywheeled cultivator as hereinafter explained and illustrated. It may also be combined with a sled on runners, and is' then particularly serviceable onsteep hillsides, on rock y or very rou h ground, or otherwise Where a wheeled imp e- The herein. 7 I

,Among its essential features the apparatus comprises a set .of burners and a frame to carry the same guards for the burners, to prevent them from striking large rockson the ground; shields at each side of the burnb and means to raise.

ers, to protect the crops and lower the various parts, to allow turning, to adjust the burners, and to lift the apparatus dver rocks and stum s.

6 necessity for some of the 45. ratus having burners which are weeds It may be explained, w1th respect to the parts hereinafter described, that in certain countries, such for example as Hawaii, crops such as sugar cane are often planted in very rocky and uneven ground, and the construction of an ap a- I intende to pass close enough to the ground to burn and grass must include devices for protecting the burners so that they will not be y. t n racks, me a. w or pile of plants.

The nvention is: ustrate pan-yingrdrawings, in which.

The tank for the kerosene or other liquid fuel is indicated-at 14, carried in any convenient manner on the frame, and it is charged with sufficient air under pressure to force the liquid to the( burners, through pipe 15 which is provided with connections to including especially a flexible pipe 16 to allow the burners and frames to be. raised and lowered. I A cross rod 17 is connected between the is used) and this rod extends through the front ends of dra bars 18 arranged to swing up and down. he'rear ends of the drag bars are twisted and bent as at 19 to run flatwise over the ground, and on rough ground, particularly, this arrangement is superior to wheels, as the drag bars will run smoother and causev less jerks and bouncing than urnersisteadier. tical arm 20 with a series'of holes 21, and the burner frame is supported by these arms. Braces 18 prevent lateral sway of the drag bars.

29 extending through selected holes 21. in the arms20; and'so the frame maybe raised or A rocking frame for supportmg'the burners i is formed byfront and rear bars'26 and 27 3 v and side bars 28. The latter have trunnions lowered byfchanging the trunnions entholes, whereby the distance of the burners, from the ground is varied. And the frame may be rocked or tilted by means of a latch lever 30, fulcrumed on one of the drag bars and connected to the frame by a-link 31 and arched bar 32. By this means the burners ma be swung up or down, from or to the groun the frame rocking on the trunnions.

The burners'are .indicatedkat 33 and are arranged in a row across between the drag bars, and may be of any suitable type, having a downwardly directed-nozzle or flame. Each burner is supplied with fuel by a branch pipe 34 from the pipe 16. The burners and pipes are immediately supported by a light auxiliary frame shown particularly in Fi .4, and consisting of a lower part with cross ars 35 and end pieces 36, and of upper cross bars 37. 28 of the larger frame, and the ipes 34 are clamped between the bars 35 an 37 by bolts 38. As shown, the auxiliary frame is arched, to raise the middle burners to conform to the ridge of soil (or rocksreferred to) between the rows. Each su plfyi pipe has a hand valve 39 to control t e: ow. Swivel unions 41 ilanable the burners to be set at proper a es.

0 protect the burners from contact withlarge rocks and other obstacles in the row, a

- series of guard bars are provided. These .s'crfiibed', the hoisting are clamped to the front bar 26 of the frame,

by means of bolts 41, the ends of the bars being bent around said front bar, and extend thence rearwardly between and below the burners, being given a quarter twist so as to not interfere with the flames. In passing over a large rock, say, the guards will ride up over'the rock and so lift the burners above the same and so prevent injury thereto.

As stated, the apparatus is intended to run between rows of crops, and to protect the same side shields are provided, each of which consists of a lead bar 42 and a sheet metal plate 43. The lead bar is pivotally connected at its front end to the cross rod 17 and bolted at its rear end to the sideof the shield plate, which is shaped located beside the row of burners. Asstrip or shoe 44 is secured along theweari edge of the shield, and is bent up at the ront end to afford means for connection to the hoisting bail 24, b means of short chains '45. These chains as ow a certain amount of independent movement of the shields, incident to rough ground or rocks, but enable the shields to be lifted with the rest of the a paratus when desired, In Figs.- 5 and 6 t e sled construction is shown;1lhe burners, frames and shields and connections are the same as "above dedevices being-modified, however. The sled runners are indicated at 50, the rod 17 being connected between the .rear ends thereof and thetank'being carried and ta ered to travel over the ground edgewise, an

in suitable hangers thereon. The hoisting devices comprise .a lever 51 pivoted to one standard of an upright frame 52 (mounted on the runners) and connected to a chain 53 which passes over a pulle 54 on the frame and is connected to the ball 24. A spring 55 normally lifts the lever, and a spring 56 holds the chain taut on the pulley. When the lever is swung down, the burner frame etc. will be lifted, and may be held in raisedposition bycatching the lever in the rack 57. This sled construction will be found particularly serviceable on very rough or hilly ground, where a wheeled frame would not travel well.

The ogpration of the ap aratus is believed to be $11 ciently evident min the above description. Obviously the number of burners ma be'increased or. decreased as desired, an various changes or modifications of the structure may be made within the scope of the invention. 1'

The holes in the front 'end of the drag bars 18 and braces 18 are preferabl slightly larger than the cross rod 17, and the same is true of the holes 21 with res ect to the trunnions 29. By this means t egtrailing frame is not ri id but will allow the drag bar 19 on either si e to lift up or down in consequence of minor inequalities or stones on the ground without tilting the frame as a whole or unduly straining the same. This feature is decidedly advantageous in working on rough of stony ground.
